` (ci. 21o- 182) 2 Claims.
This invention relates to a filter cleaner and is more particularly designed for use on the type of pressure filters employed in dry cleaning establishments for filtering the cleaning solution from the washer.
The principal object of the invention is to provide a simple and highly efficient device which can be quickly and easily applied to any dry cleaners pressure iilter and which, when operated, will vibrate the lter screens therein to loosen adhering foreign matter so :that the latter may settle to the bottom .of the filter.
Another object of the invention is to provide a device of this character which will not interfere with the normal userof the lter and which can be operated while the filter is in operation.
Other objects and advantages reside in the detail construction of the invention,- which is designed for simplicity, economy, and eiiiciency. These will become more apparent from the following description.
In the following detailed Idescription of the in-v vention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in al1 views of -the drawing and throughout the description.
In the drawing:
Fig. 1 is a side view of a typical dry cleaners pressure filter with the side thereof broken away to illustrate the internal mechanism;
Fig. 2 is a fragmentary perspective view illustrating the improved filter cleaner in place in the filter;
p Fig. 3 is a detail view of the 'shaker bar employed in the improved cleaner; and
Fig. 4 is an enlarged detail -section Villustrating one of the ibearings employed in the improved filter cleaner.
In Fig. 1 a typical iilter housing is illustrated at I0, with its clean-out at I I, lid at I2, outlet manifold at I3, inlet at I4, lter screens at I5, and discharge at 21.
The improved filter cleaner is applied to the above filter by drilling a single hole through one side of the housing I between the innermost lter screens I5 and adjacent the top thereof. A nipple I6 is welded about the threaded hole to receive a suitable stuffing gland I1. A shaft IB is passed through the stuffing gland I 'I and the nipple I6 into the interior of the housing III.
The shaft I8 extends parallel to the planes of the filter screens I5 and terminates in a bearing sleeve I9, which is Welded or otherwise secured to the inner face of the opposite Wall of the housing l0, as shown in detail in Fig. 4. The shaft I8 is 2 provided with la shoulder 20 a-djacent its inner extremity, and a cap 2| is threaded on the sleeve I9 so as to overlap the shoulder 20 and hold the extremity of the shaft IB in place in the sleeve.
The projecting extremity of the shaft I8 carries a suitable hand crank 22, by means of which it may bel rotated from the exterior of the housing I0. An eccentric cam is mounted on the shaft I8 at the middle of the housing IU.
A shaker :bar 24 overlaps, and rests by gravity on, the top edges of all of the filter screens I5, the bar being -provided with suitable notches 25 in its bottom edge for overlapping the upper edges of the screens. 'Ihis shaker bar is formed with two cam arms 2'6 at its middle which extend downwardly on each side of the cam 23.
In use, the solution `to be filtered enters the intake I4 and flows through the filter screens I5 into the hollow interior thereof, then `descendsinto the outlet manifold I3 and discharges from the discharge 2l. All 0f the lint and other foreign matter in the solution piles upon the filter screens I5. This deposit restricts the flow of solution and interferes with efficient filtering action.
It can be readily seen if the hand crank is rapidly rotated at intervals, it will, through the action of the eccentric 23, reciprocate the shaker bar 24. The latter, due to the notches 25 fitting the lter screens, will impart a rapid vibration to the screens, which loosens the accumulated material and allows it to settle to the clean-out I I.
While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent is:
1. A device for cleaning filter screens of the at, vertical, parallel, separated type used in dry lcleaners pressure filters comprising: a horizontal shaker bar lying across the upper edges of all of said screens at right angles to the planes thereof, there Ibeing notches in the lower edge of said shaker bar for receiving the upper edges of said filter screens; a shaft `extending across said filter at right angles to said shaker bar; means on said shaft for imparting a longitudinal and horizontal reciprocation to said shaker bar; and means for rotating said shaft from the exterior of said lter.
2. A device for cleaning filter screens of the fiat, vertical, parallel, separated type used in dry cleaners pressure filters comprising: a horizontal shaker bar lying across the upper edges of all of said iter at right angles to and below said shaker Y REFERENCES, CITED The following references are of record in the nie of this patent:
